I don't know if this will help you .....maybe you already have the info.... Back quite a few months ago, I did a lot of searching on this Loomis family...in particular, O. H. Loomis and where he came from. His father was Selah Loomis, born 1785, Tolland, Ct. His mother was Esther Howard. You will find them all in the 1850 census of Henry Co, Illinois. In 1840, I believe they were in St. JosephCo, White Pidgeon Prairie Twp, Michigan. Selah and Esther had a large brood of kids which I discovered on the Ancesteral File. O. H. (Orren Howard) Loomis appears as O. N. Loomis, in the 1850 Henry Co census next to his father, Selah. It doesn't appear that he came out to Illinois with your Horatio G. Sanford. Do you have info on where Horatio was and when? I see an index reference to a Horatio G. Sanford in Essex Co, Gloucester, Mass page 511 for the 1860 census. Is this your guy? Since Selah Loomis had so many kids....among them some daughters, perhaps Horatio was the nephew of O. H. Loomis????? Just a thought. Although I'm not actively searching this family right now...they didn't pan out for my search...at least not for now....I would entertain any additional questions you might have for locating people.....will see what I can do.
